| magnesium | <chemical, element> An essential divalent cation. The major role is as the chelated ion in ATP and presumably other triphosphonucleotides. The magnesium ATP complex is the sole biologically active form of ATP. The other essential role of magnesium is as the central ion of chlorophyll. Cellular concentration is less than 5mM. Serum concentration approximately 1mM. Pharmacologic action: Hypomagnesemia can cause refractory ventricular fibrillation or ventricular tachycardia. Uses: known hypomagnesemic states - suspect hypomagnesmia in alcoholics, chronic disease states, or others with poor nutrition; treatment of choice for Torsade de Pointes. Dose: 1-2 grams IV push for cardiac arrest, over 1 to 2 minutes for Torsades, and over 5 to 60 minutes for acute myocardial infarction. Potential complications: Transient flushing and diaphoresis, sinus bradycardia, hypotension, hyporeflexia and paralysis with overdose. Abbreviation: Mg (15 Mar 2000) |

| magnesium chloride | <chemical> Magnesium chloride. An inorganic compound consisting of one magnesium and two chloride ions. The compound is used in medicine as a source of magnesium ions, which are essential for many cellular activities. It has also been used as a cathartic and in alloys. Chemical name: Magnesium chloride (MgCl2) (12 Dec 1998) |

| magnesium compounds | Inorganic compounds that contain magnesium as an integral part of the molecule. (12 Dec 1998) |
| magnesium deficiency | Can occur due to inadequate intake or impaired intestinal absorption of magnesium. Low magnesium (hypomagnesaemia) is often associated with low calcium (hypocalcaemia) and low potassium (hypokalaemia). Deficiency of magnesium causes increased irritability of the nervous system with tetany (spasms of the hands and feet, muscular twitching and cramps, spasm of the larynx, etc.). According to the national academy of sciences, the recommended dietary allowances of magnesium are 420 milligrams per day for men and 320 milligrams per day for women. The upper limit of magnesium as supplements is 350 milligrams daily, in addition to the magnesium from food and water. (12 Dec 1998) |
| magnesium excess | Persons with impaired kidney function should be especially careful about their magnesium intake because they can accumulate magnesium, a dangerous situation. According to the national academy of sciences, the recommended dietary allowances of magnesium are 420 milligrams per day for men and 320 milligrams per day for women. The upper limit of magnesium as supplements is 350 milligrams daily, in addition to the magnesium from food and water. (12 Dec 1998) |
